Small Block Valve Covers

People can’t see the beautiful porting artistry inside your Chevrolet Performance aluminum cylinder heads, but they can, and do, see the valve covers. To make sure your GM engine looks as great as it runs, Chevrolet Performance offers a wide selection of precision-engineered, branded valve covers. The valve covers are either aluminum or stamped steel. They’re designed to seal tightly and minimize the chance of oil leakage. Taller competition valve covers are made to easily clear high performance valvetrain components.
